SLUB CATCHER FOR SPOOLERS.

Application filed October 12, 1928. Serial N0.'312,031.

This invention relates to a device for clearing the yarn or removing the slubs in the operation eta spooler or other similar textile machine.

The object of the invention is to provide a simple and practical form of device which will act definitely and positively to clear the yarn.

The object of the invention is further to provide such a device which shall be adapted to clear yarns of various sizes.

The object of the invention is further to provide such a device which itself may readily be cleaned.

These and other objects and features of the invention will appear more fully from the accompanying description anddrawings and will be particularly pointed out in the claims.

Since yarn-clearing and slub-removiug devices are well known in connection ith spoolers and other similar textilemachines it is unnecessary to illustrate and describe a machine to which the device of this invention is applied. All that is shown for that purpose is the usual traverse rod of a spooler upon which the yarn guiding and clearing devices are mounted.

A. simple and preferred form of construction embodying the present invention is shown connected to the traverse rod and it is. of course, understood there will he as many of these devices as there a re yarns running through the machine.

In the drawings, Fig. 1 is a side elevation of the device;

Fig. 2 is a front elevation;

3 is a top plan view;

Fig. 4 is a detail in elevation showing on an enlarged scale a portion of the lower guide bar;

Fig. 5 is a fragmentary view showing another arrangement of the clearing passage:

Fig. 6 is a fragmentaryview showing a third arrangement of the clearing passage.

A traverse rod 1 of the ordinary spooler is illustrated as the means for supporting the yarn clearer or slub catcher or remover with which this invention is concerned.

The device as illustrated comprises a two part bracket, the parts 2 and 3 of which embrace the traverse rod and are clamped there to by means of the set screw 4: so as to hold the device in the desired working position.

The bracket part 2 carries near its free end a guide rod 5 extending laterally parallel with the traverse rod 1.

The yarn clcari ug elements comprise a pai r of superimposed guide bars 6 and 7. These guide bars present somewhat extended juxtaposed faces and preferably this result is secured by making each of the bars of sub: stantially square cross section. The lower bar 7 has a shank extending into the bracket part 2 and is locked in place by a set screw :3 threaded into the bracket part. The upper guide our 6 is iiivotally mounted on the lower bar by means of a screw 9 extending theret-hrough and threaded into the lower bar. This screw 9 has mounted thereon beneath its head a helical spring 10 seated in a recess in the guide bar 6 so that the upper guide bar (3 is l eld in close contact with the lower guide bar by means of this spring. The two guide bars extend laterally from the bracket part 2 parallel with the traverse rod.

A yarn clearing passage is formed between the two guide bars 6 and 7 and preferably as illustrated in Figs. 3 and 4 there are a plurality of these passages of different crosssectional areas thus to accommodate yarns 01' different sizes.

In the preferred construction illustrated in Figs. 1 to at grooves 10, 11, 12 and 13 are formed in the upper face of the lower bar and extend transversely thereof those grooves diminishing in diameter, the groove 10 being shown as the largest and the groove 13 as the smallest. -When the upper guide bar 6 is closed upon the lower guide bar it will be seen that there are formed a plurality of yarn-clearing passages each of which is bounded by the juxtaposed faces of the two guide bars and that these juxtaposed faces immediately adjacent each passage are in contact thus preventing the passage of yarn between the guide bars except through one 01": the yarn-clearing passages.

Fig. 5 illustrates a construction in which a yarn-clearing passage is formed by the transverse groove 14 entirely in the upper guide bar while Fi 6 illustrates a form in which the yarn-guiding passage 15 is formed partially in each guide bar but it will be seen that in all cases the result is the same.

With the plurality of yarn-clearing passages it is desirable that means be provided to direct the yarn through a desired or selected yarn-c1earing passage. Such a means is shown as a flat plate 16 having an upstandmg project-ion 17 provided with a guide opening 18. This guide plate is slotted at 19 and adjust-ably connected to one of the guide bars, as the lower guide bar 7, by means of the set screw 20 so that its guide opening 18 he brought into alignment with either of the yarn-clearing passages and thus act to direct the yarn therethrough.

Whenever it is desired to insert the yarn between the guide bars and into one of the yarn-clearing Massages and whenever it is desired to remove the yarn or to clean the device l rom sluhs or collections of lint the set screw released. and the upper guide her 6 swung on the s t screw as a pivot to open position as illustrated in Fig. 3.

There thus presented a very simple, practical and eiiicient device. /Vhatever size of yarn may be employed. a yarn-clearing passage of suitable size may be selected and the guide plate 16 adjusted to direct the yarn therethrough. The sharp edges of the entrance of the yarn guide passage formed by the superimposed guide bars ellectively 1,'e moves sluhs and clears the yarn. There is nothin about the device that is likely to get out of order or to be damaged in use. l Vhenever necessary any part may easily be replaced as each part is of a simple construction.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters l aten'lr is:

l. A yarn clearer comprising a pair oi superimposed guide bars having a plurality of yarn clearing passages of different crosssectional area extending transversely 0i and bounded by the juxtaposed races 01 said hars wit-h the said juxtaposed faces immediately adjacent said passages contacting to prevent the passage oi the yarn except through said passages.

2. A yarn clearer comprising the construction defined in claim 1 together with yarnguiding means longitudinally adjustable of said bars to direct the yarn through a select ed one of said passages.

3. A yarn clearer comprising the construction defined in claim 1 together with a yarnguide secured to and longitudinally adjustable or one of said. bars to direct the yarn through a selected one of said passages.

l. 2i yarn clearer comprising the construction defined claim 1, in which there is a pivotal connection between said hars to perniit the separation oi the sed i ces 1M ning the yarn passag 5. A yarn clearer coin'irising a pair of superimposed guide bars havii'ig a plurality oi? grooves extending transversely oi the upper oi the lower bar, the lower face of the upper bar closing said grooves to :torm yarn-clearing passages and immediately adjacent said g ooves contact g with the upper face of the lo'u bar to prevent the passsage of yarn except through said passages.

e. A yarn clearer comprising the construction defined in clain'i 5 together with a yarn guide secured to and longitudinally adjustable the lower bar to direct the yarn through a selected one 01" said grooves.

7. ii yarn clearer comprising the construction defined in claim 5 in which the said grooves are oi dili'erent cross-sectional area and in which a yarn guide is provided, secured to and longitudinally adjustable or" the lower bar to direct the yarn through a selected one of said grooves.

8. A yarn clearer comprising a pair of superimposed guide bars having a yarnclearing passage extending transversely of and. bounded by the juxtaposed faces of said bars with the said juxtaposed faces immediately adjacent said passage contacting to prevent the passage of the yarn except through said passage.

in testimony whereof, I have signed my name to this specification.
